These are levels only, i don't plan on porting weapon textures or models of any sort

You forgot to clean-up the RocketLauncher ammo and weapon model + textures and the cannonball ammo textures.

Lava Golem, Biomechs and harpy still use alpha models, Marsh Hoppers and Fishes use earlier textures, that were previously only seen on some screenshots, other enemies that you didn't mention only use different/early sounds and animations

@Yay8 I believe that this build was not cleaned up from any of the alpha stuff like enemies and weapons, unless it was replaced by newer version. Nigmas on “Serious Sam Classics” discord server made a gallery map (for the leaked build) that contains every leftover enemy and weapon (and missing classes), if you want to take a look yourself.

very interetsing version

ohh ok

@renato.wertheim As I already said these are levels from the recently leaked build that showed up on archive.org , and are unfinished/in early state. Which is the most noticeable when you look Sand Canyon (Yellow Terrain) which is very noticeably rearranged.

im confused are those levels not in the main game

Also the levels are disabled in Network/Split Screen menus as they work properly only in singleplayer

@_$a\/@(g)E- This is how it looks like with nothing but this addon installed: imgur.com/GTVNSww

what is the first level's name in the map list i could only find a name called level 1 and when i load it i'm in some kind of out of bounce area is this a bug or i'm loading the wrong map?

Woow! Very nice
